Be it known .that I, FRANK KINzACH, a.

citizen oftheUnitedStates,`- residing at- Statc fof TeX-as, haveinventedanew and useful Machine for :Cleaning Pipe-Lines, of

which the 'follow-ing is "a specification.4 iThis in lv'fenti-t)`cleaning. the exterior surfaces `of plpe lines.

vOnefoflfthe objects ofthe present. invention is to provideaflnachineadapted. to travel along pipe line, sai-d pipeline being lused"asa track for themachina-and kthe said 1nachi-ne 'carrying a l cleaning.structure which extends aronndthe Iplpe supporting the maf. chineandis'- adapted to rotate for thepur.-

, Y0"y spring 12 Which serves to -bind the Wheels l1 v13 adapted toreceive motion' through a pinion 19,1e'ceives motion, through a gear 20,fromp a transverse shaft 21'A having a Wormnvheel 22"!nesh1ng with andadapted4 to be driven by a Worin 23. rlhis Worin is secured to ashaft 24driven by the motor 9 and which canbe coupled to or uncoupled from themotor by a clutch under the con trol o fa foot lever 25.

Secured to therear end portionof the platform 1 is the upper half of a'bearing sleeve 26- having outstanding terminal anges 27 to 'Whih are`detaohably securedl corresponding flanges 28 extending from' the -endofthe lower section 29 of -sald sleeve.

Brackets 30' extend outwardly from the upper and lower sections of thebearing sleeve and constitute guides for rack bars 31. Each' of theserack bars has a foot 32 at its lower end While its upper or toothed endportion engages agear Both of the `gears 32 are secured toa transversesha-ft 33 aud'between these gears 32aud secured' to .the shaft 33 is aWorin gear 34 meshing with a worm which is loosely mounted on the 'shaft34 and has a clutch member 36 at one end thereof.` The Worm 23 is also Q.Leos

loosely mounted. on 4the shaft 24 and has a clutch.. member 3,7. Mountedon'the lshaftaiid between the two worms 23 and35 is a drive gear 38having opp'ositely extending inFig 1 theclutch ymembers 37 and 3 9 arelin engagement with each other. so that the .'treme position', ho wever,tlie worm 23 loev coineslnn'coupled from A itsshaftand the clutchmembers 39 and 40 projecting from the hub portion thereof. A yoke 41projectsa '1 into a groove 42 formed inthe clutch mem'- loer.; 39. andthis yoke ris adapted to be shifted by a lever 43 so as to move. gear 38to a desired position. It will be understood that when the gear 38 isinthe position shown worm23 is thus couple'dpto the shaft 24. When thegear 38 is moved to its other eX- clutch member 40 ,engages the clutchmeinber 36 thus to couple lthe worm 25 to the 20,

On

each of these piiis'are jou'rnaled arms 4S arranged in pairs andconstituting bearings' for. toothed cutters '49. One or both ends ofeachcutter. can be tapered as Shown fat 50.iiiFig .'1. Secured to' eachof the pins 47 S0 vas to be fixed relative thereto, are fingers I 51land interposed between these viingersjand wardly upon said arms 48 so asto hold the cutters 49-yieldingly against the pipe P.

It isito be understood that when the maA chinei's not in use .the gear38 canbe out 0f mesh with the gear 46 and the feet` 32 can be inengagement with the ground. By shifting the clutchmembei-.40'intoengage` .ment with the clutch memberv 36,tl`ie racks x 3l can be raisedinasmuch as motion will -tlius be transmitted from the rotating shaft 24t0 the worin'gearing controlling the operation of the rack bars. Afterthe rack barshave been elevated, the gear 38`caii be shifted into meshwith the gear 46,thu`sv simultaneously coupling said gear 46 to theshaftf24 -and vCoupling-the worm 23 .to said-shaft- -Asa result thetubular driving 'member44 will be rotatedwithin the sectional bearing'member 2642.9 and' motion will'be transmitted through the gearing tothe propelling wheels ll. y .Thus the machine 'removed from thel pipe.

will be caused to move forwardly and, dur- .ingv said movement', thegear4 `i` and the parts connected thereto will be rotated about the`pipe. it lvill cause` the'cutters 49` which are pressed `against thepipe, to loosen any incrustations thereon so that they will thus beremoved and thc pipe left in a clean condition. As the machineapproachesa joint` the wheels 4 can be successively raised by means of theirlevers 7 so they can pass over y the joint without correspondinglyelevating the platform 1.

It will be understood-that by disconnect# ing theiianges 27 and'28, thesections of the tubular member 44 caiibc detached and. I

By having the bea-ring member 2G and tubular transmission member 44 madeof upper and lower secu tions, said members can readily be placed on orremoved from the pipe I). v

It has been found that by utilizing` a ina* chine such as described, apipe linev can be thoroughly cleaned by machine and a great .saving-oftime thus effected.

By providing 'the kcutters 'with tapered ends, saidfcuttersfwill ridereadily over the pipe joints.v 'By referring particularly to Fig. 2 itvwill-befnote'd that the inner side edges of the treads; of thewheels-'4 engage the' outer surface of pipe'aiid tend to bitev:thereiiitof `thus:1 holding" the' machine properly centered on the pipeso that it will not -slide .laterally thereon. v.
